hi,
I compiled kernel 2.6.9 using 2.4.8 kernel on redhat9. During compilation everything worked as expected. But when i boot newly compiled kernel sound dosent start and i cant mount vfat fs. both of these services are built as modules during compilation. Also screen resolution is low in X.
i tried both using standered configuration file and menual config. I compiled for 5 times but got the same result. whats wrong??? Plss help. Thanx in advance.

I have good news and bad news. First, the bad news:

There are significant differences between the 2.4 and 2.6 series kernels. You can't simply compile & install as if this where newer 2.4 release. There are changes (most notably the handling of device files) that require more action on your part. If you have done all this, my apologies, but your post doesn't seem to indicate that.

The good news:
I found a document online that describes the process of migrating from a 2.4 kernel to a 2.6 one. You can find it here. It is a multi-page document. So be sure to read through everything. Like I said, it's not a trivial upgrade...

Copy the .config file from the old kernel source into the new kernel root do a make oldconfig change the stting to what you need when it asks, then do a make && modules && modules_install. copy the (kernel root)/arch/i386/boot/bzImage to your boot dir or link it, mod your LILO/GRUB.conf and reboot

Thanx a lot for yr help
